Scrutineering
In its simplest form, 'scrutineering' is a way of standardising craft performance in order to make the competition fair and equally matched. Scrutineering involves inspecting and checking the craft, the motor, and accessories (including fuel type) for compliance to the specifications outlined in competition guidelines.
It is carried out by competition officials a few days prior to competition. No team may enter a craft into competition without its first passing scrutineering. Officials look for modifications to the motor, confirm correct fuel type, and check that all craft carry the minimum list of IRB accessories.
